CHARLES T. WVESTLAKE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO COM- MONWVEALTH STEEL COMPANY, OF ST. LOUIS, MISSOURI, A OOR- PORATI ON.

CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 773,309, dated October 25, 1904.

Application filed June 6, 1904. Serial No. 211,428. (No model.) I

To all writ 771, it may concern;

Be it known that I, OHARLEs T. WEsrLAKE, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Car-Trucks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to improvements in car-trucks; and, briefly statechit consists in sectional chairs and sectional spring-seats for supporting the ends of a truck-bolster within the side frames and a bolster supported by said members.

Figure I is a side elevation of a car-truck side frame with my bolster shown supported therein upon my improved chair and springseat. Fig. II is a horizontal section taken on irregular line II II, Fig. I. Fig. III is a perspective view of one end of my bolster. Fig. IV is a perspective view of one of the springseat sections. Fig. V is a perspective view of one of the bolster-chair sections. Fig. VI is a perspective View of a modification of one of the bolster-chair sections. Fig. VII is a view, partly in plan and partly in horizontal section, illustrating a bolster supported upon the modified bolster-chair sections.

1 designates the pedestal-bar of a car-truck, and 2 is a truck side frame seated upon said pedestal-bar. The side frame is preferably of diamond form, as seen most clearly in'Fig. I,

and it includes a pair of columns 3 and a bottom chord 4.

5 designates a pair of spring-seat sections that are mounted within the side frame 2 between the columns 3, each section being provided with a pair of vertical ribs or legs 6, that straddle the bottom chord 4 of the side frame. Each spring-seat section also has two side walls 7, surmounting the flat portion of the section, and end wall 8 and vertical lips 9, that extend beyond said end wall and straddle one of the side-frame columns 3. (See Figs.

I and Surmounting the flat portions of the spring-seat sections are bosses 10, that receive the holster-supporting springs 11.

12 designates a pair of bolster-chair sections.(see Figs. I, II, and V) that surmount the springs 11. Each of these chair-sections has a flat portion that rests upon said springs,

and the outer end of each section extends upjacent to its ends and at its sides with vertically-grooved notches 17, that receive the ribs 15 of the chair-sections.

By the herein-described construction of the parts of a car-truck I am enabled to readily and quickly mount the truck-bolster in the truck, for the reason that the bolster may be introduced into the space between the truck side-frame columns, while the members by which it is to be supported are absent from the space or partially absent therefrom. The spring seats and chairs which constitute the carrier members of abolster with the springs positioned between them may then be readily put in place beneath the bolster, due to their being of sectional form, and when they are so placed will be firmly held to the side frames, due to their engagement with the side-frame columns and bottom chord.

In Figs. VI and VII, I have shown a modification of my bolster-supporting chair suitable for use in connection with bolsters that are narrower at their end than throughout their central portions. In this modification, 12 designates the chair-sections having the guide-head 13, bearing the ribs 15. The ribs are provided with vertical enlargements 15", extending transversely thereof to fit into the grooves 17 of the narrow bolster ends 16, as seen in Fig. VII, the enlargements serving as a widened bearing for the bolsters, which is rendered necessary due to the sides of the bolster being too remote from the heads of the bolster-chair sections to bear thereagainst.

1 claim as my invention- 1. The combination with a side frame and its columns, of a bolster-chair consisting of sections and having engagement With said columns, and a spring-seat consisting of sections and having engagement with said columns, substantially as set forth.

2. The combination with a side frame including its columns and bottom chord, of a spring-seat consisting of sections having engagement with said columns and bottom chord, and a bolster-chair consisting of sections having engagement With said columns, substantially as set forth.

3. The combination With a side frame including its columns, of a bolster having an end positioned between said columns and pro vided with vertical grooves at its sides, a chair consisting of sections having engagement With said columns, and ribs forming parts of said chair-sections and fitting in the grooves of said bolster, substantially as set forth.

4. The combination With a car-truck including its columns and bottom chord, of a spring seat consisting of sections having ribs embracing said bottom chord, and lips embracing said columns, substantially as set forth.

5. The combination with a truck side frame containing a bolster-opening, of a chair consisting of sections and located in said opening in engagement with its Walls, substantially as set forth.

6. The combination Witha truck side frame having a bolster-opening, of a swing-seat arranged in said opening and consisting of sections having engagement With the Walls of the opening, substantially as set forth.
